The Audison Prima APX 690 features an exclusive 40 mm horn loading dome tweeter that contributes to maximize efficiency of up to 96dB SPL and an acoustic lens specifically designed and applied to the tweeter to increase dispersion in the high frequency range.
To strengthen the emission of very high frequency ranges otherwise affected by off-axis positioning compared to the listening point, the APX 690 featuring a supertweeter.
Audison Prima APX 690 - Product Features
- PEI (Polyethylene injected) supertweeter employed to strengthen emission of very high frequency ranges otherwise affected by off-axis positioning common to rear deck installations.
